PRIORITY CLAIM

The present disclosure claims priority to Chinese Patent Application No. 202010213783.7, titled “METHOD, APPARATUS, MEDIUM, AND DEVICE FOR VEHICLE AUTOMATIC NAVIGATION CONTROL”, filed on Mar. 24, 2020, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to Internet of Vehicles technology, and more particularly, to a method, apparatus, medium, and device for vehicle automatic navigation control.

BACKGROUND

Vehicles based on automatic navigation technology, when having same starting point and destination, often form a platoon at the starting point. The platoon can be understood as a straight line of one vehicle after another, and can then automatically navigate, in the form of a platoon, from the starting point to the destination where the platoon is disbanded.

When vehicles automatically navigate in the form of a platoon, the air resistance experienced by vehicles in the platoon that are blocked by other vehicles can be reduced, and thus the vehicles experiencing reduced air resistance can have lower fuel consumption.

However, with different starting points and/or destinations, vehicles (or platoons) will move separately even if they have an overlapping segment of driving route, and thus the air resistance experienced by the vehicles cannot be effectively reduced, resulting in suboptimal fuel saving effects for the vehicles.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following, the solutions according to the embodiments of the present disclosure will be described clearly and completely with reference to the figures. Obviously, the embodiments described below are only some, rather than all, of the embodiments of the present disclosure. All other embodiments that can be obtained by those skilled in the art based on the embodiments described in the present disclosure without any inventive efforts are to be encompassed by the scope of the present disclosure.

It is to be noted that a vehicle moving in the front of a platoon can be referred to as a leading vehicle, and other vehicles can be referred to as following vehicles. The leading vehicle automatically navigates according to a predetermined navigation route, and a vehicle-mounted server on the leading vehicle can transmit location information and driving information (including, but not limited to, steering wheel angle information, throttle control amount information, and brake control amount information) of the vehicle where it is located to the vehicle-mounted server of each following vehicle in accordance with a predetermined time length, such that each following vehicle can follow the movement of the leading vehicle. Every time the location information and the driving information are received, the vehicle-mounted server on each following vehicle can use a location corresponding to the received location information as a navigation target location, and when it reaches the navigation target location, control the vehicle to move according to the received driving information, so as to achieve automatic navigation of the platoon.

It is to be noted that when forming a platoon at a starting point, the vehicle-mounted server on the leading vehicle can randomly set an order (which can be denoted as an ID) in which each following vehicle follows the leading vehicle.

In order to maintain the distance between vehicles in the platoon, the vehicle-mounted server on the leading vehicle can at least transmit, according to the order in which each following vehicle follows the leading vehicle, to the vehicle-mounted server of that following vehicle a vehicle-mounted server identifier of a following vehicle immediately following it. The vehicle-mounted server on the leading vehicle or each following vehicle can transmit location information to the vehicle-mounted server on the following vehicle immediately following it based on the corresponding vehicle-mounted server identifier in accordance with a specified time length.

The vehicle-mounted server on each following vehicle can determine a distance to the vehicle (leading or following vehicle) it immediately follows based on the obtained location information of the vehicle it immediately follows and its own location information, and report the determined distance to the leading vehicle, such that the leading vehicle can control the speed of each following vehicle based on the received distances, thereby maintaining the distance between vehicles in the platoon.

When vehicles automatically navigate in the form of a platoon, the air resistance experienced by vehicles in the platoon that are blocked by other vehicles can be reduced, and thus the vehicles experiencing reduced air resistance can have lower fuel consumption.

However, with different starting points and/or destinations, vehicles (or platoons) will move separately even if they have an overlapping segment of driving route, and thus the air resistance experienced by the vehicles cannot be effectively reduced, resulting in suboptimal fuel saving effects for the vehicles.

The inventors of the present disclosure found that, even if the starting points and/or destinations of the vehicles (or platoons) are different, the vehicles (or platoons) can also form a platoon and move together, so as to reduce air resistance as much as possible and reduce fuel consumption.

For example, even if the starting points and/or destinations of the vehicles (or platoons) are different, their navigation routes may partially overlap. On the overlapping navigation routes, the vehicles (or platoons) can also form a platoon and move together, so as to reduce air resistance as much as possible and reduce fuel consumption.

As another example, even if the selected navigation routes are different and thus the navigation routes do not overlap, given the same destination, the vehicles (or platoons) can also form a platoon and move to the same destination according to the same navigation route, so as to reduce air resistance as much as possible and reduce fuel consumption.

Therefore, the present disclosure provides a solution for dynamically forming vehicles (or platoons) into a platoon in a process of automatic navigation, so as to achieve vehicle automatic navigation control. With this scheme of vehicle automatic navigation control, expansion of a platoon of autonomous vehicles can also be achieved. For example, one vehicle may form a platoon with another vehicle or join a platoon of vehicles, a platoon of vehicles may follow one vehicle to form a platoon, or a platoon of vehicles may join another platoon of vehicles.

In the following, the present disclosure will be described in further detail with reference to the figures, such that the objects, solutions, and advantages of the present disclosure will become more apparent. Obviously, the embodiments described below are only some, rather than all, of the embodiments of the present disclosure. Starting from the embodiments of the present disclosure, those skilled in the art can obtain other embodiments without applying any inventive skills and all these embodiments are to be encompassed by the scope of the present disclosure.

Embodiment 1

Embodiment 1 of the present disclosure provides a method for vehicle automatic navigation control. The method can be applied to a vehicle automatically navigating according to a predetermined navigation route. The entity for performing the method can be referred to as a vehicle-mounted server (which can also be referred to as a first vehicle-mounted server, which can be understood as a vehicle-mounted server requesting to form a platoon). The vehicle can be a vehicle that moves alone or a leading vehicle in a platoon with one or more following vehicles. The step flow of this method is shown in FIG. 1, which includes the following steps.

At step 101, automatic navigation information is received.

In this step, the first vehicle-mounted server can receive at least one piece of automatic navigation information.

One piece of automatic navigation information can be understood as corresponding to a vehicle automatically navigating according to a predetermined navigation route. The vehicle can be a vehicle that moves alone or a leading vehicle in a platoon with one or more following vehicles.

One piece of automatic navigation information can contain a navigation route, a destination, a current location, and a vehicle-mounted server identifier of a corresponding vehicle. It can be appreciated that the automatic navigation information can contain a navigation route, a destination, and a current location, and a vehicle-mounted server identifier corresponding to a vehicle automatically navigating according to a predetermined navigation route.

In this embodiment, the automatic navigation information may be automatic navigation information reported by each vehicle automatically navigating according to a predetermined navigation route, received periodically by a platooning control system and transmitted periodically to other vehicles automatically navigating according to their respective predetermined navigation routes.

At step 102, a matching vehicle-mounted server identifier is determined.

In this step, a vehicle-mounted server identifier of a vehicle to form a platoon with a vehicle where the first vehicle-mounted server is located can be determined based on automatic navigation information corresponding to the vehicle where the first vehicle-mounted server is located and the at least one piece of automatic navigation information as received. An information overlapping degree between automatic navigation information of the vehicle to form the platoon and the automatic navigation information corresponding to the vehicle where the first vehicle-mounted server is located meets a predefined requirement.

In this step, in order to determine the vehicle-mounted server identifier of the vehicle to form the platoon based on the automatic navigation information corresponding to the vehicle where the first vehicle-mounted server is located and the at least one piece of automatic navigation information as received, the automatic navigation information having an information overlapping degree meeting the predefined requirement can be determined first, and then the vehicle-mounted server identifier contained in the determined automatic navigation information can be the vehicle-mounted server identifier of the vehicle to form the platoon.

If there are at least two pieces of automatic navigation information that are determined to have the information overlapping degree meeting the predefined requirement, one of them can be selected in any arbitrary manner, e.g., a random one can be selected or the one having the highest overlapping degree of the navigation route can be selected.

In a possible implementation, the automatic navigation information having the information overlapping degree meeting the predefined requirement can be determined by, but not limited to: determining, from the received at least one piece of automatic navigation information, automatic navigation information containing a navigation route overlapping the navigation route corresponding to the first vehicle-mounted server and containing a current location within a predefined range, or automatic navigation information containing a destination identical to the destination corresponding to the first vehicle-mounted server and containing a current location within a predefined range.

It can be appreciated that the automatic navigation information corresponding to a vehicle having the at least partially overlapping navigation route and the current location within the predefined range can be determined. That is, the vehicle having the at least partially overlapping navigation route and the current location within the predefined range can be determined as the vehicle to form the platoon.

The predefined range for the current location can be set as required.

For example, in a possible implementation, the current location being within the predefined range can be understood as the current location being on the overlapping navigation route and the distance between the current location and the end point of the overlapping navigation route (in this embodiment, the distance can be understood as a length of a path on which the vehicle can move) not being smaller than a first threshold, and on the path on which the vehicle where the vehicle-mounted server receiving the automatic navigation information is located moves, in the direction pointing to the end point of the overlapping navigation route, the current location being before the location of the vehicle where the vehicle-mounted server receiving the automatic navigation information is located, and the distance between the current location and the location of the vehicle where the vehicle-mounted server receiving the automatic navigation information is located not being greater than a second threshold.

Thus, before reaching the end point of the overlapping navigation route, the vehicle corresponding to the automatic navigation information can serve as a leading vehicle of the vehicle where the vehicle-mounted server receiving the automatic navigation information is located, and form a platoon with the vehicle where the vehicle-mounted server receiving the automatic navigation information is located to move on the overlapping navigation route.

In another example, in a possible implementation, the current location being within the predefined range can be understood as the current location being located before the starting point of the overlapping navigation route, and the distance between the current location and the starting point of the overlapping navigation route not being greater than a third threshold. Thus, it can form a platoon with the vehicle where the vehicle-mounted server receiving the automatic navigation information is located in a timely manner to move on the overlapping navigation route.

In addition, automatic navigation information corresponding to a vehicle with a same destination and a current location within a specified range can be determined, that is, the vehicle with the same destination and the current location within the specified range can be determined as the vehicle to form the platoon.

The specified range for the current location can also be set as required.

For example, in a possible implementation, the current location being within the specified range can be understood as the distance between the current location and the location of the vehicle where the vehicle-mounted server receiving the automatic navigation information is located not being greater than a fourth threshold.

Thus, the vehicle where the vehicle-mounted server receiving the automatic navigation information is located can travel a short path to form the platoon with the vehicle corresponding to the automatic navigation information in a timely manner, so as to avoid increase in the fuel consumption of the vehicle where the vehicle-mounted server receiving the automatic navigation information is located.

At step 103, a platooning request is transmitted.

The platooning request is transmitted to a vehicle-mounted server (which can be referred to as a second vehicle-mounted server) corresponding to the determined vehicle-mounted server identifier of the vehicle to for the platoon, to request forming the platoon with the vehicle corresponding to the vehicle-mounted server. The platooning request can be understood as carrying an identifier corresponding to the vehicle-mounted server transmitting the platooning request, such that the vehicle-mounted server receiving the platooning request can feed back information to the vehicle-mounted server corresponding to the identifier.

At step 104, the vehicle is controlled to move as a following vehicle.

After the platooning request is transmitted, if the vehicle-mounted server receiving the platooning request agrees to form the platoon, it can determine the vehicle where the vehicle-mounted server transmitting the platooning request is located as a following vehicle, and feed back location information and driving information based on the vehicle-mounted server identifier carried in the platooning request, in accordance with a predetermined time length. The driving information may contain, but not limited to, steering wheel angle information, throttle control amount information, and brake control amount information.

Then in this step, a platooning response containing the location information and the driving information can be received and in accordance with the platooning response received each time, the vehicle where the first vehicle-mounted server is located can be controlled to move as a following vehicle of the vehicle where the vehicle-mounted server transmitting the location information and the driving information is located.

This step can be understood as receiving the location information and the driving information, and each time the location information and the driving information are received, the location corresponding to the received location information can be used as the navigation target location, and when the navigation target location is reached, the corresponding vehicle is controlled to move in accordance with the received driving information.

It is to be noted that the first vehicle-mounted server may also periodically report a distance between the vehicle where it is located and a vehicle in front of it in the platoon while controlling the vehicle where it is located to move as a following vehicle of the vehicle where the vehicle-mounted server transmitting the location information and the driving information is located, such that the leading vehicle can adjust the speed of each vehicle in the platoon to avoid collision or increase in inter-vehicle distance.

Therefore, in this step, the location information can be received in accordance with a specified time length, and each time the location information is received, the distance between the location corresponding to the received location information and its corresponding location can be determined, and the determined distance can be reported to the vehicle-mounted server transmitting the location information and the driving information.

It can be understood that after the vehicle-mounted server receiving the platooning request agrees to form the platoon, the vehicle where the vehicle-mounted server transmitting the platooning request is located can be regarded as the last following vehicle, and the order information of the following vehicles in the platoon can be updated.

If the vehicle where the vehicle-mounted server agreeing to form the platoon is located has no following vehicle before agreeing to form the platoon, then the vehicle where the vehicle-mounted server agreeing to form the platoon will be the vehicle for the vehicle where the vehicle-mounted server transmitting the platooning request is located to immediately follow. The vehicle-mounted server agreeing to form the platoon can transmit the location information of the vehicle where it is located to the vehicle-mounted server transmitting the platooning request in accordance with a specified time length.

If the vehicle where the vehicle-mounted server agreeing to form the platoon has one or more following vehicles before agreeing to form the platoon, then before agreeing to form the platoon, the last following vehicle of the vehicle where the vehicle-mounted server agreeing to form the platoon is located will be the vehicle for the vehicle-mounted server transmitting the platooning request is located to immediately follow. The vehicle-mounted server agreeing to form the platoon can instruct the vehicle-mounted server on the last following vehicle of the vehicle where it is located before agreeing to form the platoon to transmit the location information of the vehicle where it is located to the vehicle-mounted server transmitting the platooning request in accordance with a specified time length.

In this embodiment, the vehicle-mounted server agreeing to form the platoon may transmit the identifier of the vehicle-mounted server transmitting the platooning request to the vehicle-mounted server on the last following vehicle of the vehicle where it is located before agreeing to form the platoon. The vehicle-mounted server can transmit the location information of the vehicle where it is located the corresponding vehicle-mounted server based on the received vehicle-mounted server identifier in accordance with a specified time length.

Of course, if the vehicle where the vehicle-mounted server agreeing to form the platoon has one or more following vehicles before agreeing to form the platoon, the vehicle-mounted server agreeing to form the platoon can transmit the location information of the last following vehicle of the vehicle where the vehicle-mounted server agreeing to form the platoon is located before agreeing to form the platoon to the vehicle where the first vehicle-mounted server is located in accordance with a predetermined time length.

That is, in this embodiment, in a possible implementation, the vehicle-mounted server agreeing to form the platoon can obtain the location information of each following vehicle, and according to the order of each following vehicle in the platoon, transmit the location information of the vehicle in front of that following vehicle to that following vehicle in accordance with the predetermined time length.

In addition, it is to be noted that if the vehicle where the vehicle-mounted server transmitting the platooning request is a leading vehicle in a platoon and has one or more following vehicles, each following vehicle in the platoon can move as a following vehicle of the vehicle where the vehicle-mounted server transmitting the platooning request is located.

In another possible implementation, the following vehicle in the platoon can alternatively move as the following vehicle of the vehicle where the vehicle-mounted server agreeing to form the platoon is located.

If it is determined that the vehicle where the first vehicle-mounted server is located has one or more following vehicles, in order to allow each following vehicle in the platoon to move as a following vehicle of the vehicle where the vehicle-mounted server agreeing to form the platoon is located, in a possible implementation, the platooning request may further carry the one or more vehicle-mounted server identifiers corresponding to the one or more following vehicles of the vehicle where the vehicle-mounted server transmitting the platooning request is located. That is, the platooning request may further carry the one or more vehicle-mounted server identifiers corresponding to at least one following vehicle. Here, the one or more vehicle-mounted server identifiers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located as carried in the platooning request correspond to the order in which each following vehicle of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located.

The vehicle-mounted server receiving the platooning request may also transmit the location information and the driving information to the vehicle-mounted server corresponding to the vehicle-mounted server identifier corresponding to the at least one following vehicle in accordance with a predetermined time length, such that the following vehicle of the vehicle where the vehicle-mounted server transmitting the platooning request is located can follow the vehicle where the vehicle-mounted server receiving the platooning request is located.

Of course, after the first vehicle-mounted server receives the platooning response containing the location information and the driving information, it can stop transmission of location information and driving information to the one or more vehicle-mounted servers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located, such that the one or more vehicle-mounted servers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located control the vehicle where the vehicle-mounted server is located to move as a following vehicle of the vehicle where the second vehicle-mounted server is located in accordance with the received platooning response containing the location information and the driving information.

In addition, each following vehicle of the vehicle where the vehicle-mounted server transmitting the platooning request is located can still report information on a distance to the vehicle in front of that following vehicle to the vehicle-mounted server transmitting the platooning request.

In another possible implementation, the information on the distance to the vehicle in front of each following vehicle may alternatively be reported to the vehicle-mounted server agreeing to form the platoon.

In order to allow each following vehicle of the vehicle where the vehicle-mounted server transmitting the platooning request is located to report the information on the distance to the vehicle in front of that corresponding following vehicle to the vehicle-mounted server agreeing to form the platoon, in a possible implementation, the vehicle-mounted server transmitting the platooning request can transmit the vehicle-mounted server identifier corresponding to the automatic navigation information to that following vehicle, notifying that following vehicle to report the information on the distance to the vehicle-mounted server corresponding to the vehicle server identifier.

That is, after the first vehicle-mounted server receives the platooning response containing the location information and the driving information, it can further transmit the vehicle-mounted server identifier of the second vehicle-mounted server to the one or more vehicle-mounted servers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located, to instruct each of the one or more vehicle-mounted servers corresponding to the one or more following vehicles to report a distance to the second vehicle-mounted server. The distance is a distance, determined by the vehicle-mounted server corresponding to that following vehicle each time it receives location information in accordance with a specified time length, between a location corresponding to the received location information and its corresponding location. Here, the location information received by the one or more vehicle-mounted servers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located in accordance with the specified time length is location information corresponding to a vehicle in front of that corresponding following vehicle.

The location information received by the one or more vehicle-mounted servers corresponding to one or more following vehicles of the vehicle where the first vehicle-mounted server is located in accordance with the specified time length can be described as follows: the second vehicle-mounted server instructs, in accordance with the order in which each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located (as the one or more vehicle-mounted server identifiers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located as carried in the platooning request correspond to the order in which each following vehicle of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located, and the order in which each following vehicle of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located can be determined), the vehicle-mounted server on the vehicle in front of that corresponding following vehicle to transmit the location information to the vehicle-mounted server on that corresponding following vehicle in accordance with the predetermined time length.

Alternatively, the location information received by the one or more vehicle-mounted servers corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located in accordance with the specified time length can be described as follows: the second vehicle-mounted server transmits, in accordance with the order in which each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located, the location information of the vehicle in front of that corresponding following vehicle to the vehicle-mounted server on that corresponding following vehicle in accordance with the predetermined time length.

In this embodiment, it is also to be noted that after the vehicle-mounted server receiving the platooning request agrees to form the platoon, and before the vehicle where the vehicle-mounted server transmitting the platooning request is located, as the following vehicle, feeds back the location information and the driving information in accordance with the predetermined time length, it can be further determined that the distance between the vehicle where the vehicle-mounted server transmitting the platooning request is located and the last vehicle of the platoon it belongs to is not greater than a threshold, so as to ensure that the distance between vehicles in the platoon is small and the air resistance and accordingly the fuel consumption can be further reduced. At the same time, in order to prevent other vehicles from cutting in line and blocking movement of the vehicles, it can be determined that the speed difference is not greater than a threshold, so as to avoid collision or increase in the inter-vehicle distance.

The vehicle-mounted server receiving the platooning request may determine that the distance between the vehicle where the vehicle-mounted server transmitting the platooning request is located and the last vehicle in its platoon is not greater than a threshold, and that the speed difference is not greater than a threshold in e.g., any of the following schemes.

When the second vehicle-mounted server determines to agree to form the platoon, it can determine whether the vehicle where the second vehicle-mounted server is located has one or more following vehicles before agreeing to form the platoon. If the vehicle where the second vehicle-mounted server is located has no following vehicle before agreeing to form the platoon, it can transmit a prompt message to the first vehicle-mounted server transmitting the platooning request in accordance with a specific time length. The prompt message carries location information and speed information of the vehicle where the second vehicle-mounted server is located. If the vehicle where the second vehicle-mounted server is located has one or more following vehicles before agreeing to form the platoon, it can instruct a vehicle-mounted server on the last one of the one or more following vehicles of the vehicle where the second vehicle-mounted server is located before agreeing to form the platoon to transmit a prompt message to the first vehicle-mounted server transmitting the platooning request in accordance with a specific time length. The prompt message carries location information and speed information of the last following vehicle.

In response to receiving a confirmation message transmitted from the first vehicle-mounted server transmitting the platooning request, location information and driving information of the vehicle where the second vehicle-mounted server is located can be transmitted to the first vehicle-mounted server transmitting the platooning request in accordance with the predetermined time length.

Here, the confirmation message is transmitted by the first vehicle-mounted server transmitting the platooning request after controlling, each time the prompt message is received, the vehicle where the first vehicle-mounted server is located to approach a location corresponding to the location information carried in the prompt message and controlling, when a distance between the vehicle where the first vehicle-mounted server is located and the location corresponding to the location information carried in the received prompt message is not greater than a threshold, a difference between a speed of the vehicle where the first vehicle-mounted server is located and a speed corresponding to the speed information carried in the prompt message not to be greater than a threshold.

It can be understood that the confirmation message can be transmitted by the vehicle-mounted server transmitting the platooning request after controlling, each time the prompt message is received, the vehicle where the first vehicle-mounted server is located to approach the location corresponding to the location information carried in the prompt message and controlling, when the location corresponding to the location information carried in the received prompt message is located before the location corresponding to the vehicle where the first vehicle-mounted server is located on the route of the vehicle where the first vehicle-mounted server is located in the direction in which the vehicle where the first vehicle-mounted server is located is moving (that is, in the direction pointing to the end point of the overlapping navigation route when the determined automatic navigation information corresponds to partially overlapping navigation routes, or in the direction pointing to the destination in the case of the same destination) and the distance between the vehicle where the first vehicle-mounted server is located and the location corresponding to the location information carried in the received prompt message is not greater than the threshold, the difference between the speed of the vehicle where the first vehicle-mounted server is located and the speed corresponding to the speed information carried in the prompt message not to be greater than the threshold.

According, in this embodiment, the following step may be performed after step 103 and before step 104.

At step 104′, the vehicle is controlled to adjust the location and the speed.

In this step, the vehicle-mounted server transmitting the platooning request can receive a prompt message in accordance with a specific time length, the prompt message carrying location information and speed information, and control, each time the prompt message is received, the vehicle where the vehicle-mounted server is located to approach a location corresponding to the location information carried in the prompt message, control, when a distance between the vehicle where the vehicle-mounted server is located and the location corresponding to the location information carried in the received prompt message is not greater than a threshold, a difference between a speed of the vehicle where the vehicle-mounted server is located and a speed corresponding to the speed information carried in the prompt message not to be greater than a threshold, and transmit a confirmation message to the second vehicle-mounted server.

Further, when the overlapping navigation route ends, or when the destination is reached, the dynamic platooning of the vehicles (or platoons) can be ended.

That is, in this embodiment, step 105 may be further included.

At step 105, a request to quit the platoon is transmitted.

If the navigation route corresponding to the vehicle-mounted server receiving the platooning request at least partially overlaps the navigation route corresponding to the first vehicle-mounted server, the first vehicle-mounted server transmitting the platooning request can transmit, when determining that its corresponding location is a specified location in an overlapping part of the navigation routes, e.g., the destination or some location close to the destination, a request to quit the platoon to the vehicle-mounted server receiving the platooning request, and determine a navigation target location based on its corresponding navigation route.

If the destination corresponding to the vehicle-mounted server receiving the platooning request is the same as the destination corresponding to the first vehicle-mounted server, the first vehicle-mounted server transmitting the platooning request can transmit, when determining that the its corresponding location is its corresponding destination, a request to quit the platoon to the vehicle-mounted server receiving the platooning request.

Of course, if the vehicle where the first vehicle-mounted server is located was a leading vehicle previously, then after quitting the platoon, the vehicle where the first vehicle-mounted server is located can move as the leading vehicle again.

In this case, when transmission of location information and driving information to the vehicle-mounted server corresponding to each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located has been stopped, after the request to quit the platoon is transmitted, transmission of the location information and the driving information to the vehicle-mounted server corresponding to each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located can be resumed, such that the vehicle-mounted server corresponding to that following vehicle controls that following vehicle to move as a following vehicle of the vehicle where the first vehicle-mounted server is located in accordance with the location information and the driving information.

When the vehicle-mounted server identifier of the second vehicle-mounted server has been transmitted to the vehicle-mounted server corresponding to each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located, after the request to quit the platoon is transmitted, the vehicle-mounted server identifier of the first vehicle-mounted server can be transmitted to the vehicle-mounted server corresponding to each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located, to instruct each of the one or more vehicle-mounted servers corresponding to the one or more following vehicles to report a distance to the first vehicle-mounted server. The distance is a distance, determined by the vehicle-mounted server corresponding to that following vehicle each time it receives location information in accordance with a specified time length, between a location corresponding to the received location information and its corresponding location.

Embodiment 2

Embodiment 2 of the present disclosure provides a method for vehicle automatic navigation control. The method can be applied to a vehicle automatically navigating according to a predetermined navigation route. The entity for performing the method can be referred to as a vehicle-mounted server (which can also be referred to as a second vehicle-mounted server, which can be understood as a vehicle-mounted server accepting a request to form a platoon). The vehicle can be a vehicle that moves alone or a leading vehicle in a platoon with one or more following vehicles. The step flow of this method is shown in FIG. 2, which includes the following steps.

At step 201, a platooning request is received.

In this step, the vehicle-mounted server corresponding to the selected automatic navigation information can receive the platooning request.

The platooning request is transmitted by a vehicle-mounted server (i.e., a first vehicle-mounted server), after receiving at least one piece of automatic navigation information each containing a navigation route, a destination, a current location, and a vehicle-mounted server identifier of a corresponding vehicle, and determining, based on automatic navigation information corresponding to a vehicle where the first vehicle-mounted server is located and the at least one piece of automatic navigation information, a vehicle-mounted server identifier of a vehicle to form a platoon with the vehicle where the first vehicle-mounted server is located, an information overlapping degree between automatic navigation information of the vehicle to form the platoon and the automatic navigation information corresponding to the vehicle where the first vehicle-mounted server is located meeting a predefined requirement, to the second vehicle-mounted server corresponding to the determined vehicle-mounted server identifier of the vehicle to form the platoon. The platooning request can carry a vehicle-mounted server identifier corresponding to the first vehicle-mounted server.

At step 202, it is determined whether to agree to form the platoon.

After receiving the platooning request, it can be determined in this step whether to agree to form the platoon.

In this embodiment, the determining condition can be set as needed, and it can be determined whether to agree to form the platoon according to whether the set determining condition is met.

In a possible implementation, the platooning request may carry a specified parameter, and the operation of determining whether to agree to form the platoon may include: determining whether the specified parameter meets a predetermined requirement.

The specified parameter may include, but not limited to, at least one of the following parameters: a vehicle type, a power system parameter, a braking system parameter, a positioning accuracy, a positioning delay, a control system accuracy, a control system delay, a lane-changing instruction version, an acceleration/deceleration instruction version, a queue management instruction version, a number of vehicles requesting to join the platoon, etc.

If it is determined to agree to form the platoon, the method can proceed with step 203.

At step 203, location information and driving information are transmitted periodically.

In this step, the location information and driving information of the vehicle where the second vehicle-mounted server is located can be transmitted to the vehicle-mounted server transmitting the platooning request based on the vehicle-mounted server identifier carried in the platooning request in accordance with a predetermined time length. The driving information may contain, but not limited to, steering wheel angle information, throttle control amount information, and brake control amount information.

Of course, when the platooning request further carries one or more vehicle-mounted server identifiers respectively corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located, the one or more vehicle-mounted server identifiers respectively corresponding to the one or more following vehicles of the vehicle where the first vehicle-mounted server is located corresponding to an order in which that following vehicle follows the vehicle where the first vehicle-mounted server is located, in this step, the location information and the driving information of the vehicle where the second vehicle-mounted server is located can also be transmitted to the one or more vehicle-mounted servers corresponding to the one or more vehicle-mounted server identifiers carried in the platooning request, other than the vehicle-mounted server identifier corresponding to the first vehicle-mounted server, in accordance with the predetermined time length.

It is to be noted that, if it is determined in step 202 to agree to form the platoon, the following step may also be included before step 203.

At step 202′, a prompt message is transmitted.

In this step, the prompt message can be transmitted to the vehicle-mounted server transmitting the platooning request in accordance with a specific time length. The prompt message may carry location information and speed information of the vehicle where the second vehicle-mounted server is located.

Step 203 can be performed in response to receiving a confirmation message transmitted from the vehicle-mounted server transmitting the platooning request.

Here, the confirmation message is transmitted by the vehicle-mounted server transmitting the platooning request after controlling, each time the prompt message is received, the vehicle where the first vehicle-mounted server is located to approach a location corresponding to the location information carried in the prompt message and controlling, when a distance between the vehicle where the first vehicle-mounted server is located and the location corresponding to the location information carried in the received prompt message is not greater than a threshold, a difference between a speed of the vehicle where the first vehicle-mounted server is located and a speed corresponding to the speed information carried in the prompt message not to be greater than a threshold.

Of course, the operation of transmitting the prompt message to the vehicle-mounted server transmitting the platooning request in accordance with the specific time length can be understood as follows. It is determined whether the vehicle where the second vehicle-mounted server is located has one or more following vehicles before agreeing to form the platoon, and if the vehicle where the second vehicle-mounted server is located has no following vehicle before agreeing to form the platoon, the prompt message is transmitted to the vehicle-mounted server transmitting the platooning request in accordance with the specific time length.

On the other hand, if it is determined that the vehicle where the second vehicle-mounted server is located has one or more following vehicle before agreeing to form the platoon, the vehicle-mounted server on the last following vehicle of the vehicle where the second vehicle-mounted server is located before agreeing to form the platoon can be instructed to transmit the prompt message to the first vehicle-mounted server transmitting the platooning request in accordance with the specific time length. The prompt message carries the location information and the speed information of the last following vehicle. Step 203 is performed when a confirmation message transmitted by the vehicle-mounted server transmitting the platooning request is received.

It is to be noted that if it is determined in step 202 to agree to form the platoon, then in step 203, the location information can also be transmitted periodically to the vehicle-mounted server transmitting the platooning request. Alternatively, a vehicle-mounted server on another corresponding vehicle can be instructed to periodically transmit the location information of the vehicle where it is located to the vehicle-mounted server transmitting the platooning request, and receive distance information reported by the vehicle-mounted server transmitting the platooning request.

Here, it can be determined whether the vehicle where the second vehicle-mounted server is located has one or more following vehicles before agreeing to form the platoon.

If the vehicle where the second vehicle-mounted server is located has no following vehicle before agreeing to form the platoon, the second vehicle-mounted server can transmit location information of the vehicle where the second vehicle-mounted server is located to the first vehicle-mounted server transmitting the platooning request in accordance with a specified time length.

If the vehicle where the second vehicle-mounted server has one or more following vehicles before agreeing to form the platoon, the second vehicle-mounted server can instruct a vehicle-mounted server on the last one of the one or more following vehicles of the vehicle where the second vehicle-mounted server is located before agreeing to form the platoon to transmit location information of the last following vehicle to the first vehicle-mounted server transmitting the platooning request in accordance with a specified time length, or the second vehicle-mounted server can transmit the location information of the last following vehicle before agreeing to form the platoon to the vehicle where the first vehicle-mounted server is located in accordance with the predetermined time length.

In addition, in step 203, the location information can be transmitted periodically to the one or more vehicle-mounted servers respectively on the one or more following vehicles of the vehicle where the vehicle-mounted server transmitting the platooning request is located. Alternatively, a vehicle-mounted server on another corresponding vehicle can be instructed to transmit location information to the one or more vehicle-mounted servers on the one or more following vehicles of the vehicle where the vehicle-mounted server transmitting the platooning request is located, and receive distance information reported by the one or more vehicle-mounted servers respectively on the one or more following vehicles of the vehicle where the vehicle-mounted server transmitting the platooning request is located.

That is, in accordance with the order in which each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located, the vehicle-mounted server on the vehicle in front of that following vehicle can be instructed to transmit location information to the vehicle-mounted server on that following vehicle in accordance with the predetermined time length, or in accordance with the order in which each of the one or more following vehicles of the vehicle where the first vehicle-mounted server is located follows the vehicle where the first vehicle-mounted server is located, location information of the vehicle in front of that following vehicle can be transmitted to the vehicle-mounted server on that following vehicle in accordance with the predetermined time length.

Further, a distance reported by the vehicle-mounted server corresponding to the vehicle-mounted server identifier carried in the platooning request, other than the vehicle-mounted server identifier corresponding to the first vehicle-mounted server, can be received. The distance can be a distance, determined by the vehicle-mounted server corresponding to the following vehicle of the vehicle where the first vehicle-mounted server is located each time it receives location information in accordance with a specified time length, between a location corresponding to the received location information and its corresponding location.

Further, this embodiment may further include step 204.

At step 204, a request to quit the platoon is received.

In this step, the request to quit the platoon as transmitted from the vehicle-mounted server transmitting the platooning request can be received, and according to the request to quit the platoon, transmission of location information and driving information to the vehicle-mounted server transmitting the platooning request can be stopped.

The request to quit the platoon may carry the identifier of the vehicle-mounted server transmitting the platooning request, and the vehicle-mounted server receiving the request to quit the platoon may stop transmission of location information and driving information to the vehicle-mounted server corresponding to the vehicle-mounted server identifier carried therein.

Of course, if the location information and the driving information of the vehicle where the second vehicle-mounted server is located has been transmitted to one or more vehicle-mounted servers respectively corresponding to the one or more vehicle-mounted server identifiers carried in the platooning request, other than the vehicle-mounted server identifier corresponding to the first vehicle-mounted server, in accordance with the predetermined time length, then in this step, transmission of the location information and driving information of the vehicle where the second vehicle-mounted server is located to the one or more vehicle-mounted servers corresponding to the one or more vehicle-mounted server identifiers carried in the platooning request, other than the vehicle-mounted server identifier corresponding to the first vehicle-mounted server, can be stopped.

In a possible implementation, the request to quit the platoon may further carry the one or more vehicle server identifiers respectively corresponding to the one or more following vehicles of the vehicle where the vehicle server transmitting the platooning request is located.

Of course, if it is desired that any following vehicle should continue to follow the vehicle where the vehicle-mounted server transmitting the request to quit the platoon is located, then the vehicle-mounted server transmitting the request to quit the platoon can further retransmit the location information and driving information of the vehicle where it is located to the vehicle-mounted server on the corresponding following vehicle.

In addition, after the vehicle-mounted server transmitting the platooning request transmits the request to quit the platoon, it may also stop reporting the information on the distance to the vehicle in front of it to the vehicle-mounted server agreeing to form the platoon.

The second vehicle-mounted server can stop receiving the distance reported by the first vehicle-mounted server corresponding to the vehicle-mounted server identifier carried in the platooning request.

If each following vehicle of the vehicle-mounted server transmitting the platooning request also reports the information on the distance to the vehicle in front of it to the vehicle-mounted server agreeing to form the platoon, then the following vehicle can also stop reporting the information on the distance to the vehicle in front of it to the vehicle-mounted server agreeing to form the platoon.

The second vehicle-mounted server can stop reception of the distance reported by the vehicle-mounted server corresponding to the vehicle-mounted server identifier carried in the platooning request, other than the vehicle-mounted server identifier corresponding to the first vehicle-mounted server.

In a possible implementation, the vehicle-mounted server transmitting the request to quit the platoon can transmit the identifier of the vehicle-mounted server agreeing to form the platoon to each corresponding following vehicle, to notify each following vehicle to stop reporting the distance information to the vehicle-mounted server corresponding to the vehicle server identifier.

Of course, if it is desired that any following vehicle should continue to follow the vehicle where the vehicle-mounted server transmitting the request to quit the platoon is located, then the vehicle-mounted server transmitting the request to quit the platoon can also notify the vehicle-mounted server on the corresponding following vehicle to retransmit the distance information to the vehicle-mounted server transmitting the request to quit the platoon.

In the following, the solutions provided in Embodiment 1 and Embodiment 2 of the present disclosure will be explained with reference to a specific example.

Embodiment 3

Embodiment 3 of the present disclosure provides a method for vehicle automatic navigation control. It is assumed that the vehicle where the vehicle-mounted server receiving at least one piece of automatic navigation information is located is a leading vehicle with one following vehicle, and the platoon can be referred to as a rear platoon.

The vehicle-mounted server on the leading vehicle of the rear platoon determines, from the received at least one piece of automatic navigation information, the automatic navigation information containing a navigation route at least partially overlapping its own corresponding navigation route and a current location within a predefined range. The vehicle where the vehicle-mounted server corresponding to the automatic navigation information is located is also a leading vehicle with one following vehicle, and the platoon can be referred to as a front platoon.

It is assumed that, in this case, on the overlapping navigation route (as shown by the straight line with arrow in FIG. 3, with the arrow pointing to the direction in which the platoons move), the front platoon moves in the front and the rear platoon moves behind the front platoon, individually. Then, the rear platoon can form a platoon with the front platoon to move together, and the method according to in this embodiment can further include the following steps.

In a first step, the vehicle-mounted server on the leading vehicle of the rear platoon transmits a platooning request to the vehicle-mounted server on the leading vehicle of the front platoon.

The platooning request may carry the vehicle-mounted server identifier corresponding to the leading vehicle in the rear platoon, the vehicle-mounted server identifier corresponding to the following vehicle in the rear platoon, and specified parameters.

In a second step, the vehicle-mounted server on the leading vehicle of the front platoon determines whether to agree to form the platoon.

After receiving the platooning request, the vehicle-mounted server on the leading vehicle of the front platoon determines whether each of the specified parameters meets a corresponding predetermined requirement, and if so, determines to agree to the form the platoon.

In a third step, after the vehicle-mounted server on the leading vehicle of the front platoon determines to agree to form the platoon, it assigns an ID to each vehicle in the rear platoon, and determines the leading vehicle in the rear platoon as the second following vehicle in the platoon, and the following vehicle in the rear platoon as the third following vehicle in the platoon.

In a fourth step, the vehicle-mounted server on the leading vehicle of the front platoon instructs the vehicle-mounted server on the last following vehicle before agreeing to form the platoon (that is, the last following vehicle in the front platoon) to transmit a prompt message periodically to the vehicle-mounted server on the leading vehicle of the rear platoon.

In a fifth step, the vehicle-mounted server on the leading vehicle in the rear platoon controls the vehicle where it is located to adjust location and speed according to the received prompt message until the distance to the last following vehicle in the front platoon is small and the speed is close to the speed of the last following vehicle in the front platoon, and transmits a confirmation message to the vehicle-mounted server on the leading vehicle of the front platoon.

In a sixth step, after receiving the confirmation message, the vehicle-mounted server on the leading vehicle of the front platoon transmits the location information and driving information of the vehicle where it is located to the leading vehicle and the following vehicle in the rear platoon periodically.

In a seventh step, the leading vehicle and the following vehicle in the rear platoon move as following vehicles of the leading vehicle of the front platoon in accordance with the received location information and driving information.

According to the solutions provided in Embodiments 1˜3 of the present disclosure, it is possible to combine one platoon with another easily and safely, such that the fuel saving effect of each platoon can be improved, and the fuel consumption can be effectively reduced.

Correspondingly to the methods according to Embodiments 1˜3, the following apparatus are provided.
